Introduction to Internet Of Things (IoT)

Internet technology connecting devices, machines and tool to the internet by means of wireless technologies.

Over 9 billion 'Things' connected to the Internet, as of now.

'Things' connected to the Internet are projected to cross 20 billion in the near future.

Unification of technologies such as low-power embedded systems,cloud computing, big-data, machine learning, and networking.

An interconnected network of physical object (lights, fans, sensors etc.) and virtual component (Virtual Machines, Simulated Object etc) which has to ability to communicate over the Internet and share information with each other is know as an Internet of Things.



Origin of Terminology

In the 2000s, we are heading into a new era of ubiquity, where the "users" of the Internet will be counted in billions and where humans may become the minority as generators and receivers of traffic. Instead, most of the traffic will flow between devices and all kinds of "things", thereby creating a much wider and more complex Internet of things. 

The title of the report was "Internet of Thing"

Discussed the possibility of internet connected M2M connectivity networks, extending to common household devices.

Some areas identified as IoT enablers :
  • RFID
  • Nanotechnology,
  • Sensors,
  • Smart Networks.

IoT Architecture-Cloud Analytics



Characteristics

Efficient, scalable and associated architecture
Unambiguous naming and addressing
Abundance of sleeping nodes, mobile and non-IP devices
Intermittent connectivity
